Saving A Picture?

What are some of the possible ways to save a picture to a file using VC++.

The easiest file type to use is Targa...I don't have any code for writing it, but I'm sure you can work it out from this reader code:

Code:

---

bool mvcTexture::LoadFromTGA(char* pcFilename, uint nTexMode) {
        // Targa data type -- uncompressed, RGBA image; element
        // 3 is always 2.
        GLubyte    targaMagic[12] = { 0, 0, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

        GLubyte    fileMagic[12];

        // Header data.
        GLubyte    header[6];
        GLuint    bytesPerPixel;

        GLuint    imageSize;
        GLuint    tmp;
        GLint      i;
        long lComponents;

        FILE *file = NULL;
        file = fopen(pcFilename, "rb");

        // Start reading in the header, make sure we
        // have the right Targa data type. 

        if(file == NULL || fread(fileMagic, 1, sizeof(fileMagic), file) != sizeof(fileMagic) || memcmp(targaMagic, fileMagic, sizeof(targaMagic)) != 0 || fread(header, 1, sizeof(header), file) != sizeof(header)) {
                fclose(file);
                return false;
    }

        // Determine width and height from header data.

        m_nWidth  = header[1] * 256 + header[0];
        m_nHeight = header[3] * 256 + header[2];

        // Determine color bit depth of the image (24 or 32).

        if(m_nWidth <= 0 || m_nHeight <= 0 || (header[4] != 24 && header[4] != 32)) {
                fclose(file);
                return false;
        }

        m_nBPP = header[4];
        bytesPerPixel = m_nBPP / 8;
        imageSize    = m_nWidth * m_nHeight * bytesPerPixel;

        m_pucImageData = (GLubyte *)malloc(imageSize);

        if(m_pucImageData == NULL || fread(m_pucImageData, 1, imageSize, file) != imageSize) {
                if(m_pucImageData != NULL) {
                        free(m_pucImageData);
                }

                fclose(file);
                return false;
        }

        for(i = 0; i < imageSize; i += bytesPerPixel) {
                tmp = m_pucImageData[i];
                m_pucImageData[i] = m_pucImageData[i + 2];
                m_pucImageData[i + 2] = tmp;
        }

        fclose (file);

It needs a little tidying up to change to use new instead of malloc, but that shouldn't be too hard.

PS: Targa files are stored as BGR, not RGB... ;)
